All Halocha Shailos and Tefilla Questions

[avromie7]

The food does tend to leak occasionally. That being said, fish cooked in a clean fleshing pot is pareve in any case. Some have a minhag to use a dedicated fish pot but it is doubtful that minhag would apply here (safek yad soledes, etc.).

Many of not most  poskim would not allow sous vide on shabbos (shehiya, hatmana bedavar hamosif hevel) some are more lenient. Ask your LOR.

And can be eaten with dairy?

all discussed at length in the Food and Recipe thread.

130 degrees is a safek Yad soledes both according to Rav Moshe and Rav Aharon and therefore it is treated as Yed Soledes Lechumrah (in other words, for basar v'cholov and issur bishul/shehiyah on shabbos, but we would also consider it not Yad solodes lechumrah, in that it wouldn't be considered mevushal to reheat in conventional methods)

I would not be macir regarding the minhag some have to have a separate fish pot when there is a safek if it leaks and safek yad soledes.

I was not refering to that chumrah. I was only answering that the fish would be considered fleishig and cannot be eating with milchig and also about Shabbos.

I would be ok with treating the fish as pareve if the pot hasn’t been used with meat in 24 hours.
See Pri Megadim S”D 95:2 regarding 3 NATs. His reasoning should apply here as well since there is no chashash that the fish touches the actual pot. Certainly if it is a stam kli there is reason to be meikel ( aino ben yomo -see Gr”a- possibly 3 NATs 2 Keilim, safek yad soledes etc.)

Regarding shabbos there are definitely reasons to be machmir but regarding shehiya/ hatmana I would look into whether the heating elements inside the sous vide unit actually come to a glow (red hot) or if they operate at a lower temperature which might not be considered aish.

Yes, i am aware of that: see a prior discussion here:

A Posek that I know spoke to Rav Moshe Feinstein about it and he also pakened like the GRA's understanding of the RaMA [Others (IIRC the Aruch Hashulchan) learn the RaMA differently that he's only talking about the mixing lechatchila not the original intent of the cooking]

but he did not mention that it was aino ben yomo, and even 3 nats would not work by a ben yomo. I was correcting his misconception that "boiling" plays a role here. (Also the Pri Chadash learns that if they are all connected at the same time it's still considered the same nat, although I wouldn't be machmir like that)

The Pri Megadim is talking about a ben yomo and is mistapek that 3 NATs are mutar even according to the Rama where it is not possible for  the vegetables to directly touch the walls of the pot.

could I put some salmon in right before shabbos and then take it out right before lunch?

There is on more thing to take into consideration for putting it in right before shabbos that you'll have to make sure that it's cooked k'machal ben driso'u (1/3 cooked) before the zman, otherwise it's considered being cooked on shabbos

Not if you put it in raw right before shabbos.

[PlatinumGuy]

- How does this impact cooking for shabbos using it - i.e. given the cooler temperatures, could I put some salmon in right before shabbos and then take it out right before lunch?

Would this not be considered הטמנה בדבר המוסיף הבל? (which is definitely assur regardless of cooking stage)

In any case, covering the buttons on the machines will help render it גרופה וקטומה according to some opinions. I don't know offhand if it's necessary and if it's sufficient.

There isn't something necessarily wrong with something that will cook on Shabbos, and מאכל בן דרוסאי doesn't always help according to all opinions that is better to be machmir like.

A Sous Vide is perhaps the only cooking method where the heter of raw still applies today. The food is probably still in raw status at the shkiah, and the food can't be completely cooked for the Friday night seudah. (Assuming temperature can be raised too high, otherwise it would still require גו׳׳ק)

That is very debatable, but yes on the lenient parts at least.

Would is Sous Vide not הטמנה בדבר המוסיף הבל?

[EliJelly]

Which part?

[EliJelly]

Would is Sous Vide not הטמנה בדבר המוסיף הבל?

Why is it הטמנה and not bishul? Because it's in a bag?

[aygart]

What part?

That otherwise it does not apply now.
